+50 Free Computing Books [PDF]



Ever since mankind focused on facilitating work processes, work quality and productivity, advances in automatic information processing have not stopped. Such a vital area could not be left out of our virtual library that is why we present our large collection of computing books.

Today we can say that this scientific area affects all essential sectors of society such as transportation, telecommunications, health, education, business, information storage, process control, among others.

Computing is defined as the automated processing of information by means of computers. It is based on theoretical, practical and technological scientific knowledge that facilitates its main tasks. These are: storage, processing and transmission of data.

Computer science is divided into two main areas of development: the study and development of computer programs (logical element), called software; and, on the other hand, the physical structure of computers (physical element), called hardware.

Information processing basically consists of converting primary data into organized, meaningful and useful information. It encompasses image processing, data mining, cryptography, artificial intelligence, teleinformatics and bioinformatics.

Thus, this important scientific and technological area has facilitated the management of an immense amount of data and has become the basis for the creation of the Internet and communication technologies.

It is really difficult to find any social sector or discipline that is not affected by the advances of computing. It can be said that it has reached all public and private sectors, even domestic life.

The most important innovation in computing was the creation of the first computer by the German scientist Konrad Zuse (1941), the Z3 model, which weighed 1000 kg. It performed basic mathematical operations.

This was followed by the evolution to the personal computer in 1965, by the Italian company Olivetti, which today derives in personal computers, laptops, tablets and smartphones. Today, many cannot conceive of life without these electronic devices. This is how important this discipline is.

Its accelerated evolution in recent years has had a major impact on the lives of half of the world’s population that today has access to the Internet and at least one electronic device.

This is a consequence of being able to have immediate access to information, remote communication and to an incalculable number of transactions and operations that make life much easier.

If you are interested in this interesting subject, we recommend once again that you take a look at the computing books in PDF format, available in this section of our virtual library.

1) Algorithms Books


In computing, an algorithm is a sequence of sequential instructions, thanks to which certain processes can be carried out and respond to certain needs or decisions. They are ordered and finite sets of steps that allow a problem to be solved or a decision to be made.

Algorithms must be precise and indicate the logical order of execution of each of the steps, it must be defined and this means that if an algorithm is executed several times the same result must always be obtained, it must also be finite, i.e. it must begin with an action and end with a result or solution to a problem.

All tasks executed by the computer are based on algorithms. A software or computer program is designed based on algorithms, so that we can introduce a task into it and solve it.

2) Computer Networks Books


Computer networks or data communication networks refer to a series of computer systems connected to each other by a series of wired or wireless devices, through which you can share information in data packets, transmitted by means of electrical impulses, electromagnetic waves or any other physical means.

Computer networks can be classified in two different ways or types:
– According to their size into local area networks called LAN (small), metropolitan area networks called MAN (consisting of several LANs) and wide area networks called WAN (e.g., the Internet).

– According to the way the equipment is connected: line, bus, star and ring.

3) Computer Security Books


Computer security is the process of preventing and detecting unauthorized use of a computer system. It involves the process of protecting against intruders who use our computer resources with malicious intent or for profit, or even the possibility of accessing them by accident. Threats can come from malicious programs that are installed on the user’s computer (such as a virus) or that arrive remotely.

In the case of viruses, it should be noted that there is currently a very long list of viruses that can significantly damage any computer or computer system. For example, there are so-called resident viruses, direct-action viruses, encrypted viruses, etc.

Computer security consists of security measures, such as antivirus software programs, firewalls and other measures that depend on the user, such as activating or deactivating certain software functions.

4) Computing Books


Computing is the science that deals with the study, evaluation or expansion of technological and digital equipment. It is in charge of studying, expanding and understanding the processes of computers, in addition to the operation of peripheral equipment that can work with it.

It has a history of no more than a century, although sources claim that its beginnings date back to when machines or artifacts oriented to different calculation tasks began to be manufactured; in 1623, the first mechanical calculator was invented by a famous German mathematician named Wilhelm Schickard.

The scope of computing is incalculable, the modification in the processes of activities has already occurred and continues to advance in an unprecedented way, constantly transforming our lives and originating new personal requirements that demand us to be aware of these new resources.

5) Database Books


A database is a collection of information pertaining to the same context, arranged in a systematic way for later retrieval, analysis and/or transmission. This term was first heard in 1963, at a symposium held in California, USA.

  • Among the main characteristics of database systems are:
  • Logical and physical independence of data.
  • Concurrent access by multiple users.
  • Data integrity.
  • Security of access and auditing.
  • Backup and recovery.
  • Access through standard programming languages.

For a Database to be truly functional, it must not only store a large number of records, but they must also be easily accessible. In addition, new information and changes must also be fairly easy to make.

6) Excel Books


Excel is a computer program developed and distributed by Microsoft Corp. It is a software that allows you to perform accounting and financial tasks thanks to its functions, developed specifically to help create and work with spreadsheets.

In Microsoft’s first exploration in the creation of spreadsheets allowed to handle numerical data in a list constituted by the union of rows and columns, this was created in 1982, with the exposure of Multiplan. Giving rise 3 years later to the first version of Excel.

Excel is different from all other office programs because it allows us to work with numerical data. With the numbers we store in Excel we can perform basic arithmetic calculations and we can also apply more complex mathematical functions, or use statistical functions.

7) Hacking Books


Hacking is the set of techniques used to access a computer system by violating the originally established security measures.

Generally, when we talk about hacking we usually refer to illicit access; but hacking as such, is a set of techniques used to enter a computer system by violating the security measures, regardless of the purpose for which it is performed, it can be lawful and requested.

Ethical hacking, also known as white-hat hacking, in contrast to traditional hacking with criminal motives, focuses on programming weaknesses and software conceptual design (bugs). In the case of security testing, the focus is, among other things, on applications and web security. In addition to software, any hardware in use can be integrated into the system security testing process.
